Convert Image format in android java

Question

How do i convert Image format from within my android application activity.

I have the code to convert image format using Java, but it doesn't output the image with good quality and also similar code is not working in Android's Java.

Answer 1

You didn't post any of your code, so i have no idea what is wrong with your code. but you can convert a image to PNG or JPEG like this:

try {
   FileOutputStream out = new FileOutputStream(filename);
   bmp.compress(Bitmap.CompressFormat.PNG, 100, out); //100-best quality
   out.close();
} catch (Exception e) {
   e.printStackTrace();
}

Answer 2

For example, from Bitmap to JPG:

Bitmap bmp;
JPEG_QUALITY = 80;
bmp.compress(Bitmap.CompressFormat.JPEG, JPEG_QUALITY, out);
